Single sided painted window glass can no longer meet people's needs for visual beauty, and the biggest feature of ultra transparency is double-sided visible, which can better meet people's visual needs. It is also another major innovation in the material industry and has greater development prospects in various industries.
Surface roughness is one of the key factors affecting the transparency of the film. HANKER uses advanced production technology and precise online detection system to ensure that the surface of the film reaches nano-level smoothness. Specifically, by optimizing the calendering process parameters, such as calendering temperature, pressure and speed, the arrangement and orientation of the PET molecular chain can be effectively controlled, and the formation of surface microstructures can be reduced, thereby reducing the surface roughness. HANKER has also introduced advanced surface treatment technologies, such as plasma treatment or coating modification, to further smooth the film surface, improve light transmittance, and ensure the ultra-high transparency of the final product.
Optical performance is an important indicator for measuring the quality of ultra-clear film, which directly determines its performance in visual applications. HANKER ensures that PET film has high transmittance, low haze and excellent dispersion properties by precisely controlling the raw material formula and production process. Specifically, high-purity PET resin raw materials are selected to reduce the use of impurities and additives to avoid light scattering; the melt extrusion and stretching process is optimized to make the molecular chain highly oriented in a specific direction, improve the straight-line transmission rate of light, and reduce scattering losses. HANKER has also developed special optical-grade additives that can adjust the refractive index of the film without affecting the transparency of the film to meet the optical needs of specific application scenarios.
Mechanical properties are the basis for ultra-clear PET film to maintain structural integrity during processing and use. HANKER has achieved a comprehensive improvement in the tensile strength, tear strength, impact strength and flexibility of the film by adjusting the molecular chain structure, introducing reinforcing fibers or nanoparticles, and optimizing the stretching ratio and heat treatment process. In particular, by finely controlling the temperature and rate during the stretching process, the PET molecular chain can be prompted to form a more compact and orderly network structure, which not only enhances the mechanical strength of the film, but also maintains its excellent transparency. HANKER's silicon coating machine and PE coating machine technology can form a uniform and firm coating on the surface of the film, further improving its wear resistance and scratch resistance, and extending its service life.
Analysis of influencing factors
Surface roughness: Excessive surface roughness will cause light scattering, reduce transparency, and affect visual effects. HANKER ensures that the film surface is smooth through fine process control, light can penetrate unimpeded, and maintain high transparency.
Optical properties: High transmittance, low haze and good dispersion performance are the core advantages of ultra-transparent PET film in visual applications. HANKER ensures that the film meets specific optical requirements such as anti-reflection and anti-reflection while maintaining high transparency through raw material selection and process optimization.
Mechanical properties: Good mechanical properties are the basis for film processing, transportation and long-term use. HANKER has achieved the best balance between film strength and toughness through comprehensive technical means to ensure its stability and durability in various application scenarios.
While pursuing high performance, HANKER has always kept in mind its environmental protection responsibilities. The company has passed ISO9001 quality management system certification, ISO14001 environmental management system certification and many other international standard certifications, and uses advanced RTO (Regenerative Thermal Oxidizer) environmental protection equipment to achieve a waste gas treatment rate of up to 99.9%, effectively reducing environmental pollution in the production process. In addition, HANKER encourages all employees to participate in environmental protection practices. From product design to production process, every step strives to be green and low-carbon, supporting sustainable development with practical actions.
